20 − 2 p > −2( p + 2) + 4 p
Solution
Sure, let's solve the inequality step by step:
-
First, distribute the -2 on the right side of the inequality: -2(p + 2) + 4p becomes -2p - 4 + 4p.
-
Simplify the right side of the inequality: -2p - 4 + 4p simplifies to 2p - 4.
-
So, the inequality now is: 20 - 2p > 2p - 4.
-
Add 2p to both sides of the inequality to get all the p terms on one side: 20 - 2p + 2p > 2p - 4 + 2p simplifies to 20 > 4p - 4.
-
Add 4 to both sides of the inequality to isolate the term with p on one side: 20 + 4 > 4p - 4 + 4 simplifies to 24 > 4p.
-
Finally, divide both sides of the inequality by 4 to solve for p: 24/4 > 4p/4 simplifies to 6 > p.
So, the solution to the inequality 20 - 2p > -2(p + 2) + 4p is p < 6.
